While a public yum repository is easy to set up with S3, going private is more difficult. The privacy must be enforced by some plugin that can retrieve files from the S3 bucket using the API with stored credentials (maybe). Storing credentials can be avoided on EC2 machines that are assigned a proper role, but this is not possible in any other scenario.
Nevertheless, the first steps are common for both public and private setups:
1. Create the proper directory structure
This is achievable with the “createrepo” binary that can be installed on both RedHat and Debian-based systems (e.g. Fedora/Centos or Ubuntu). Running this program results in a “repodata” sub-directory being created with a couple of files that store parsed rpm information.
2. Sync the local repository with the S3 bucket
Going back in time to early 2000s, one can find a lot of businesses on “web hosting” or providing services directly from bare-metal servers. After all, the “cloud” only became a thing and gained traction in the last 5 to 10 years. Many such businesses survived to present day.
What was (and in many scenarios still is) the reality of being able to provide services from a colocated or on-premises bare-metal server?
The physical server had to be purchased before anything else; there were requirements on the enclosure size that sometimes prevented consumer-grade hardware from being used;
The operating system had to be installed by hand, from installation media;
The configuration was a tedious process, with many details being fixed throughout the days after going live.
Let’s assume you went against my advice from a few months ago and you actually secured that job. That’s actually quite an achievement, but it’s not what I intend to write about. What you leave behind is, most of the time, more significant than what you think is being set in front of you.
Most likely your current job does not compare with the likes of Googamazbook. That’s OK. Or you feel that you did not get to achieve everything you hoped for when you signed up for your current, soon to be previous position. That’s also OK. Let’s walk through some possible frustration points:
1. Promotions (lack of)
You do feel you deserved more and you were passed on for promotions due to unclear, maybe non-professional reasons. Most likely this is true, but it does not always have to be about you as an individual; it’s about the way companies work.
